Cosell admitted to not having much tape to look at as Tannehill started just 19 games as a quarterback but found things he liked and disliked.

His first game to watch was against Oklahoma State and he noticed Tannehill’s arm.

“Tannehill has a good arm, but not a cannon,” Cossel writes.

Likely the biggest thing scouts have noticed about Tannehill, as did Cosell, was his ability to throw on the run.

“One benefit of Tannehill’s three-quarters delivery is it allows him to throw very well on the move, both to his right and impressively, to his left,” Cosell writes. “In fact, he’s a better, more accurate passer on the run than either Andrew Luck or Robert Griffin.

“Tannehill was very efficient off the boot-action pass game. That will translate very well to the NFL.”

Overall Cosell didn’t see improvement like he would have liked to during Tannehill’s senior season. He does think Tannehill is a better prospect than Christian Ponder was last year.

“Tannehill possesses the skill set to be a quality NFL starter,” Cosell said. “At this point, he would be best in a quick-rhythm, short-to-intermediate passing game that featured play-action and boot-action passes.
“One thing we know for certain: He likely will be drafted higher than his body of work suggests he should be.”
